SE11 集中帮助/基本搜索帮助

业务要求场景，在CN22创建预留List新增一列并且有搜索帮助多个标签

一、创建两个基本搜索帮助（拿其中一个为例)

因为我这个需求是根据多张表关联获取搜索帮助数据，所以选择方法为空

1、根据值集合的对话：如果数据量大于100条就不会直接展示数据，会先展示一个筛选界面
2、 立即显示值：就是立即展示数据源表中的全部数据
3、 具有值限制的对话：搜索帮助一开始不会将数据表中的全部数据展示出了，会给个筛选条件

搜索帮助出口：通过SE37 参考函数F4IF_SHLP_EXIT_EXAMPLE拷贝新建一个常规函数

代码如下：

FUNCTION yx_f4if_shlp_exit_ccid.
*"----------------------------------------------------------------------
*"*"本地接口：
*"  TABLES
*"      SHLP_TAB TYPE  SHLP_DESCT
*"      RECORD_TAB STRUCTURE  SEAHLPRES

  DATA: lt_thead TYPE TABLE OF thead.
  DATA: lt_text_headers TYPE TABLE OF thead,
        lt_text_table   TYPE text_lh.
  DATA: s_ccid   TYPE RANGE OF yemm_ccidbh,
        s_ccidms TYPE RANGE OF yemm_ccidms.
  DATA: BEGIN OF ls_ktab,
          ccid   TYPE yemm_ccidbh,
          ccidms TYPE yemm_ccidms,
        END OF ls_ktab,
        lt_ktab LIKE TABLE OF ls_ktab.

* EXIT immediately, if you do not want to handle this step
  IF callcontrol-step <> 'SELONE' AND
     callcontrol-step <> 'SELECT' AND
     " AND SO ON
     callcontrol-step <> 'DISP'.
    EXIT.
  ENDIF.

*"----------------------------------------------------------------------
* STEP SELONE  (Select one of the elementary searchhelps)
*"----------------------------------------------------------------------
* This step is only called for collective searchhelps. It may be used
* to reduce the amount of elementary searchhelps given in SHLP_TAB.
* The compound searchhelp is given in SHLP.
* If you do not change CALLCONTROL-STEP, the next step is the
* dialog, to select one of the elementary searchhelps.
* If you want to skip this dialog, you have to return the selected
* elementary searchhelp in SHLP and to change CALLCONTROL-STEP to
* either to 'PRESEL' or to 'SELECT'.
  IF callcontrol-step = 'SELONE'.
*   PERFORM SELONE .........
    EXIT.
  ENDIF.

*"----------------------------------------------------------------------
* STEP PRESEL  (Enter selection conditions)
*"----------------------------------------------------------------------
* This step allows you, to influence the selection conditions either
* before they are displayed or in order to skip the dialog completely.
* If you want to skip the dialog, you should change CALLCONTROL-STEP
* to 'SELECT'.
* Normaly only SHLP-SELOPT should be changed in this step.
  IF callcontrol-step = 'PRESEL'.
*   PERFORM PRESEL ..........
    EXIT.
  ENDIF.
*"----------------------------------------------------------------------
* STEP SELECT    (Select values)
*"----------------------------------------------------------------------
* This step may be used to overtake the data selection completely.
* To skip the standard seletion, you should return 'DISP' as following
* step in CALLCONTROL-STEP.
* Normally RECORD_TAB should be filled after this step.
* Standard function module F4UT_RESULTS_MAP may be very helpfull in this
* step.

* STEP DISP     (Display values)
*"----------------------------------------------------------------------
* This step is called, before the selected data is displayed.
* You can e.g. modify or reduce the data in RECORD_TAB
* according to the users authority.
* If you want to get the standard display dialog afterwards, you
* should not change CALLCONTROL-STEP.
* If you want to overtake the dialog on you own, you must return
* the following values in CALLCONTROL-STEP:
* - "RETURN" if one line was selected. The selected line must be
*   the only record left in RECORD_TAB. The corresponding fields of
*   this line are entered into the screen.
* - "EXIT" if the values request should be aborted
* - "PRESEL" if you want to return to the selection dialog
* Standard function modules F4UT_PARAMETER_VALUE_GET and
* F4UT_PARAMETER_RESULTS_PUT may be very helpfull in this step.

类似在创建一个基本搜索帮助2

二、创建集中搜索帮助（注意点一定要要点击分配 不然一切都正常就是没办法把选择的数据带到页面上

三、绑定（也可以绑定表的元素里面）我这面是在dialog页面里面

如果在创建过程中有问题欢迎大家评论区留言一块讨论一块提高，感谢查看 希望对您有帮助
